GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 571,902, dated November 24, 1896.

Application filed March 20, 1896.

T 0 (all whom it may concern.-

Be it known that I, HERMAN KUHFAHL, a citizen of Germany, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

My invention has reference to improvements in gas-burners and it consists in a gasburner by which the carbon contained in the gas is rendered incandescent ina high degree, so that the burned gas gives a whiter and more brilliant light than the gas consumed by the burners now in use.

It is a well-known fact that the gas-burners do not allow a thorough combustion of the gas, as the latter does not come sufficiently in contact with the oxygen in the atmospheric air, so that the heat produced by such combustion is not intense enough to raise the carbon in the burning gas to white heat. The gas-flames obtained by the common gasburners appear reddish or yellow, as the heat produced by such burner is only able to convert the imperfectly-combusted carbon int red heat.

By my improved gas-burneraperfect white light and, in comparison with the present gasburners, a considerable economy in the consumption of gas are obtained, as to produce a certain degree of light a smaller quantity of gas is required than by the common gasburners.

My improved gas-burner is illustrated in the accompanying drawings, in which Figure l is a vertical section, and Fig. 2 a top view, of the same, the section, Fig. 1, being on line 1 1 of Fig. 2.

Similar letters of reference indicate corresponding parts.

A in the drawings represents ahollow ring, the upper end of which is left open. Those portions of the side walls of the said hollow ring which form the open end of the same are compressed so as to form a series of corrugations a, which are so arranged that the inner portions of the grooves of the said two side walls come in contact with each other and produce thereby separate openings at, as clearly shown in Fig. 2. Into these openings tapering tipsbare screwed or soldered, which Serial No. 584,098. (No model.)

tips are each provided on its top with an orifice of about twenty-four one-thousandths of an inch diameter to allow the discharge of gas. The tips form in their shape the continu- 5 5 ations of the tapers produced by the corrugations or grooves a in the side walls of the ring A, so that a series of cones having each an outlet-orifice for the gas is obtained. If desired, the tapering tips may be integral with thehollow ring. Thelatter is connected with the main gas-pipe by means of the connecting-pipe B in the same manner as the common Argand burner, and has a sleeve 0 attached to the outside of the ring, the lower portion of which sleeve extends outwardly,

so as to form a base or support for the gaschimney D, which is held in position on the said support by means of upright springs or holders d.

The base or support is provided with draftholes (1. The tips b are arranged in such distances from each other that when the gas streaming through the orifices of the same is lighted separate gas-j ets are obtained which do 7 5 not come in contact with each other, as illustrated in Fig. 1. The said separate flames appear in an entire white and brilliant light, which is produced by the perfect combustion of the gas and the conversion of the carbon into an incandescent state. This is attained by an increased air-draft, which strikes the individual flames in three diiferent ways, namely, first, through the inner opening of the ring; second, through the openings (1 of the sleeve, and, third, along the corrugations or grooves a and the terminations of the same into the cones of the burner-tips.

By the arrangement of my separate burnertips a considerably large surface of the atmosphericair is given to the whole quantity of burning gas, as each individual gas-jet is surrounded on all sides by a strong air-current. It is well known that the more thorough and energetic the draft the whiter and 5 brighter the flames and more complete the combustion.

Practical tests have been made and have fully affirmed the aforesaid statement. The light produced by my improved gas-burner has an intensity of more than twice the candle-power of a common gas-flame consuming the same quantity of gas as my burner. Another advantage of my gas-burner is that the heat, by the increased air-draft, is greatly reduced, and thereby the breakage of the gaschiinneys rendered almost impossible.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A gas-burner consisting of a hollow ring having its upper portion open and the side walls so corrugated, that the inner grooves of the corrugations meet each other and form a series of cones which are each provided with an orifice for the discharge of the gas, the hollow ring being connected by a connectingpipe with the main gas-pipe, substantially as set forth.
